Ошибка начальной загрузки Chef - 401 unauthorized

Я пытаюсь настроить узел Chef с помощью Vagrant, но при выполнении команды bootstrap возникает ошибка. Я следую руководству на learn.chef.io

Мой сервер Chef настроен на EC2 и отлично работает. Я могу успешно выгружать кулинарные книги со своей рабочей станции на сам сервер.

Однако при запуске следующей команды начальной загрузки с моей рабочей станции для настройки узла:

knife bootstrap localhost --ssh-port 2222 --ssh-user vagrant --sudo --identity-file /Users/Shivam/.vagrant/machines/default/virtualbox/private_key --node-name node1-ubuntu --run-list 'recipe[learn_chef_apache2]'

Я получаю следующую ошибку.

Это вывод трассировки стека на моей виртуальной машине Vagrant.

Вот как выглядит мой Knife.rb на моей рабочей станции.

current_dir = File.dirname(__FILE__)
log_level                 :info
log_location              STDOUT
node_name                 "chefadmin"
client_key                "#{current_dir}/chefadmin.pem"
chef_server_url           "https://ec2-11-90-25-181.compute-1.amazonaws.com/organizations/4thcoffee"
cookbook_path             ["#{current_dir}/../cookbooks"]

Я последовал совету здесь Chef bootstrap дает 401 несанкционированный доступ без везения.

Вероятно, упустил что-то простое. Заранее спасибо!
